Topband: How good is good enough

DXpediton style

take 3-4 feet of bare solid # 10 # 12 copper wire and make a loop around the 
base of the antenna support- make it larger if necessary, wrap and solder the 
ends of the loop

Wrap a couple turns from each radial around the loop wire.  Solder.  The joints 
are far enough apart to make soldering reasonably easy even with MANY radials.

If you must use a dis similar metal, use the same technique and split bolt wire 
clamps, feed two at a time through each split bolt

Run as heavy a wire as you think necessary from the ground ring to the feedline 
shield, transformer return, whatever goes to ground.
